The compressor is certainly not unfamiliar to everyone. It is a driven fluid machine that promotes low-pressure gas to high-pressure gas, and it is the heart of the refrigeration system. The compressor is an indispensable part of the refrigeration system, and the air compressor crankshaft is the power transmission component of the compressor, and it is indispensable for the compressor. Therefore, the maintenance and maintenance of the compressor crankshaft is also very important. Next, we Xinchang Fan talked about the maintenance of the compressor crankshaft.
1. Cleaning inspection after disassembly of Air compressor crankshaft
Clean. The disassembled crankshaft should be soaked in gasoline or kerosene for cleaning to scrape away residue or dirt. Air conditioner after-sales maintenance reminds, pay attention to brushing parts with copper wire brush.
an examination. During the cleaning process, carefully check the integrity of each crankshaft. The crankshaft that can be used continuously should be cleaned 2-3 times.
dry. Put the cleaned and inspected crankshaft in the tray and send it to the oven for drying treatment (the oven temperature is controlled at about 110-130 degrees, and the time is 4-5h). When taking it out, coat the crankshaft with a layer of lubricant and cover it with a clean cloth to prevent dust contamination.
2. Install after cleaning. After coating the crankshaft with lubricating oil, insert one end of the oil suction nozzle from the hole of the casing, then insert the motor rotor of the compressor into one end of the crankshaft oil suction nozzle (ie the end of the crankshaft), and then put a section of hollow thick iron pipe on it , And finally put it in a bench vise and press it in slowly.
The above is the cleaning work of the compressor crankshaft and the method of installing it back after taking it out. I hope it can help everyone. Feel free to contact us to learn more: cast iron bushing.
